Rear brake shoes
The rear brake is provided with a
wear indicator, which allows you to
check the brake shoe wear without
having to disassemble the brake. To
check the brake shoe wear, check the
position of the wear indicator while
applying the brake. If a brake shoe
has worn to the point that the wear
indicator reaches the wear limit line,
have a Yamaha dealer replace the
brake shoes as a set.

Checking the brake fluid level
Insufficient brake fluid may allow air
to enter the brake system, possibly
causing it to become ineffective.
Before riding, check that the brake
fluid is above the minimum level
mark and replenish if necessary. A
low brake fluid level may indicate
worn brake pads and/or brake sys-
tem leakage. If the brake level is low,
be sure to check the brake pads for
wear and the brake system for leak-
age.
Observe these precautions:
8
When checking the fluid level,
make sure that the top of the
master cylinder is level by turn-
ing the handlebars.
8
Use only the recommended
quality brake fluid, otherwise
the rubber seals may deterio-
rate, causing leakage and poor
braking performance.
Recommended brake fluid:
DOT 4
NOTE:
If DOT 4 is not available, DOT 3 can
be used.
8
Refill with the same type of
brake fluid. Mixing fluids may
result in a harmful chemical re-
action and lead to poor braking
performance.
8
Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the
fluid and may result in vapor
lock.
